Heroku.. almost a bad word in many circles. It's expensive, polished, and restrictive. To me: it's like the Apple of hosting providers. I can rely on it to "just work" the vast, vast majority of the time.
Why Heroku?
Managed hosting.
As a developer first, I want to get right to the meat of the business logic and start solving problems. Getting around configuring an EC2 instance for the umpteenth time is an incredible productivity boost.
It's like having your own dev ops team. Right out of the box we can leverage many managed services like automated deployments, backups, security updates, quick recovery from outages, etc.
For example, instead of spinning up an instance of Postgres, making our own backup solution, verifying it works, writing tools to make it easier to make backups before deploys, etc… we can use Heroku Postgres which comes with WAL (Write Ahead Logging) aka realtime live backups with a 4hour rollback window.
Pros:
- Extremely friendly to developers, can onboard or transfer to new people very easily
- Familiar to many developers
- Mostly painless deployments
- Integrates with many services easy, ie CircleCI
- Load balancing for free
Cons:
- Hard to customize if we have unique needs
- Relying on third parties that can go down (but, is based in the same facilities as Netflix)
Why AWS?
Control.
If you need some complicated configuration of Postgis, nginx caching, non-emphemeral local storage, yadda yadda.. it's probably easier to go straight to EC2 instances than it is plumbing some gross configuration on Heroku together.
Also, if you are running a VVIP top secret app then you will want to sandbox your code away from any prying eyes. But, in my opinion, this is rarely needed and often times for small-to-medium sized enterprises: security theater. Certainly it is another point of failure to rely on a separate service storing your code, but I'd bet on a managed host with hundreds of millions behind it.
Pros:
- Complete control -- if we want to do some funky settings on the Postgres database and use it more like a graph database, add map projections, etc. then we can do that
- No third party outages to worry about
- No third party, beyond AWS itself, has access to your code
Cons:
- More prone to human error, compared to Heroku with dozens of Dev Ops working full time to keep the pipes unclogged
- Requires a more experienced Dev Ops person to maintain
- Each setup is different, everyone has their own opinions and that means new devs take a bit longer to get spun up
Conclusion
At CKC we love simplicity and speed. Heroku brings us the capability to develop complex applications as quickly as possible, and to run those applications at scale.
